Natya-class minesweeper

The Natya-class were a group of minesweepers built for the Soviet Navy and export customers during the 1970s and 1980s. The Soviet designation was Project 266M Akvamarin. The ships were used for ocean minesweeping.

Design

The design evolved from the Yurka class minesweeper with new demining equipment including more advanced sonar and closed circuit TV. A stern ramp made recovering sweeps easier. The hull was built of low magnetic steel. The engines were mounted on sound dampening beams and shrouded propellors were used to reduce noise. An electrical field compensator was also installed. A single ship designated Natya 2 by NATO was built with an aluminium hull for reduced magnetic signature.

Project 02668

Displacement: 852 tons. Armament: 1x6 30mm gun mount AK-306, 2x1 14.5 mm machine-gun installation MTPU-1, high-speed pin sweep BKT, electromagnetic sweep TEM-4, acoustic sweep AT-3, depth charge SZ-1 or SZ-2, mine detector-finder "Livadia". Crew: 60 people.

Pr.02668 designed by Design Bureau "Almaz" and is a prototype, which demonstrates the latest technology - the logical continuation of a series of pr.266ME. The minesweeper is equipped with the most modern means of anti-mine protection. The project 02668 for the first time in the Russian mine-sweeping ships introduced integrated navigation bridge and the main command center, as well as automated control system of anti-mine action activities "Diez-E."

St. Andrew's flag-raising ceremony was held on 17.01.2009, the ship was accepted into the Russian Black Sea Fleet.[1]
